1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Background and Aims: Preoxygenation is crucial during rapid sequence induction, especially in peritonitis patients undergoing exploratory laparotomy who are prone to hypoxaemia. This study compares high-flow nasal oxygen (HFNO) versus facemask for preoxygenation efficacy, laryngoscopy duration, desaturation, arterial blood gases, and patient comfort. Methods: Sixty consenting, haemodynamically stable patients aged ≥15 years, scheduled for exploratory laparotomy, were randomised into two equal groups receiving preoxygenation using either HFNO at 50 L/min for 5 min or standard anatomical facemask (SMO) at 10 L/min. Arterial blood gas samples were obtained preoperatively, 5 min after preoxygenation, and 1 min following intubation. The primary outcome was partial pressure of arterial oxygen (PaO₂) after 5 min of preoxygenation. Secondary outcomes included partial pressure of arterial carbon dioxide (PaCO₂), peripheral oxygen saturation (SpO₂), laryngoscopy duration, desaturation incidence, patient comfort, and haemodynamic parameters. Statistical analysis was performed using independent Results: PaO Conclusion: Preoxygenation for 5 min by HFNO is superior to facemask as there is an increase in PaO
